Hey! I did download the datasheets but had a hope you guys had a cheat sheet. I’m looking at porting a bunch of sketches like abSynth-FM and they all address pins that are differently addressed on midiboy. Trial and errror, will get me there, but… hope, hope. I did get a simplified version of abSynth doing FM (I’m supposed to be working on midi stuff but it’s a hack
some addresses/constants like:
OCR4A = ((uint16_t)(0x8000 ^ dac_l) >> 8);
or
cbi(TCCR2B, CS43); // CS00 from the handbook
fail. Did I just not read the specs carefully enough (sigh).
